Ratio of quarters to dimes = 7 : 8

Or quarters : dimes : : 7 : 8

Step-by-step explanation:

Ben has a collection of 15 coins in the form of Quarters and Dimes.

So Quarters + Dimes = 15

Now there are 7 quarters in the collection then

7 + Dimes = 15

Dimes = 15 - 7 = 8

Therefore, the ratio of quarters to dimes = 7 : 8

Or quarters : dimes : : 7 : 8
